The 730 will be more efficient based on improvements to the chip design but also DDR4 uses less power than DDR3. There’s also increase in efficiency when with the v4s over the 3s

The newer chips improve efficiency in two areas. a) what they do per clock cycle (IPC) and b) power consumption at low load or idle.

Chips like the v3/v4 in the 13th gen do lag on IPC but also on pure clock speed but for most homelab servers that doesn’t matter because they’re not heavily loaded. It’s the power consumption for idle where they get crucified and yes the Xeon will use a lower more power to tick over.

There could also be a design factor there. It’s okay if your desktop goes into a deep sleep to save power but for a server responsiveness is a big factor and you don’t know when there’s going to be access so going in really low power mode isn’t a good thing because the time to come back to full power could be critical.

if you search for online power consumption caculator such as one used for sizing a a UPS you can play with different configurations and see what numbers you come up with.

And yes easily $70 more to run the 710.

But there can also be other factors. Each of the those HDDs can consume between 5 and 10w depending if they’re idle or in use. Each memory module will use 2 - 3w so if you’ve 8 x 8GB in the Dell server that’s 24w, where as say 4 x 16GB would use half that.

Your Dell also has iDrac so even if the server is shutdown, unless it’s unplugged you’ll still draw some power.

And speaking of power, the PSU effeciency has greatly improved over time. Not sure what standard PSUs Dell provided with the 710 and whether they improved them to 730 but there’s a good chance your desktop has a more efficient unit.

Next time you copy over 1TB you might start off with “Wow” before hitting the “Yawn”.

Caching is good until you fill the cache and then everything drops back to normal.

But with smaller files you probably will notice a difference

might have to check & confirm but you could probably put a high end V4 xeon in there that will give you lots of cores and ram is always that helpful.

Being the old DDR4 components you could probably pick both up for little $$$$ via ebay.

Now both that and the i9 system are massive over kill going by your current load.

Normal wisdom is that the modern consumer chips is the i9 are the way to go because they’ll perform better and use less powert (especially if the system load is load or pretty much at idle).

Your i7 system out performs the 1620v3 and uses less power in doing so.

But what you’ve got at the moment is as far as that platform goes other than perhaps a faster processor,

So then we look at the return on investment. Find an online power calculator and work out the running cost on the T5810.

Then look at the cost of the new motherboard/CPU/ram (if the Dell is using RDIMMS you can’t carry them over the i7 is DDR3) and probably a new case.

Though a new case would give new drive bays - that T5810 seems rather lacking unless there’s more hidden away than just the two at the bottom.

Then work out the running cost for a new system.

Then comparing the two work out how long it would take you to recover the costs of the new components based on power savings.

Anything over 2 years, stick the dell and upgrade down the track.

Not sure what you’re trying to do - Thunderbolt can be daisy chained so not sure why would need to put a TB card in the dock.

The enclosure is generally transparent to the OS. It just sees the devices plugged.

TechnoTim on youtube a video on rack mounting his Mac Mini (M1 model) and used an external chassis and tried different cards without issue.

You’re probably going to limited by Apple’s support (for example you can’t put in a nVidia graphics card in).

google to find a power usage calculator (often used for sizing a UPS) that will help you.

You also need to factor in other components - motherboard and chipset, each RAM stick uses 2 - 3w you’ve got system fans and inefficiencies in the PSU.

Width is standardized at 19” you just need to make sure it’s deep enough.

Most of the dells are around 27” deep and racks tend to be 25 or 35” if they’re enclosed so you’d need a 35” one.

Open frame racks can be adjusted for depth,

The decide on the height 12- 15ru should be fine for your usage.

They’re harder to find second hand so new may be the best option.

42ru cable found quite cheap (even free) but are a pain to move about hence the low price. Given they become available en mass if a data centre or similar close it’s sell to cheap to dispose of or send for scrap.

You’ll need some rails but they can be expensive or a shelf ( I use a Startech one with my 4ru server).

you’d have to use a video capture unit such as used by game streamers etc.

But what are you trying to achieve?

Unless there’s some of sort of repeating error there’s not going to be anything displayed the console. It will simply sit at the login prompt with the MOTD telling you where access the webgui.

There won’t be any output from any of the VMs or LXCs

Otherwise you might as well have a SSH shell open.

before you convert, install the virtio drivers and in the VM configuration make sure the disk image file is attached as SATA0.

The virtioSCSI is a better drive but Windows doesn’t know the device at the first boot after the migration. It needs to boot, find the device and configure the drivers.

and need to ensure the image contains all the partitions from the original drive.
